LAMP-SHADE Application filed July 8, 1930.

provide a lamp shade having a frame comprising top and bottom ring members, and

brace members adapted to be sprung into engagement with the ring members and to detachably hold the covering in place on the frame.

A further object is to provide brace members of such construction that they may be used either with or without the usualside wires of the lamp shade frame. In the latter use the brace members take the place of the side wires and provide a frame of knockdown construction which will occupy but a very small space in packing, storing and handling, and which may be readily assembled by an unskilled person without tools.

My invention is not to be limited to the details as shown and described, but extends to whatever constructions which may be included within the scope of the appended In the drawings- A Figure 1 is a view in perspective showing one embodiment of my invention;

Fig. 2 is a detailed view, on an enlarged 52 scale, illustrating the lower end of one of thebrace members;

Fig. 3 is atransverse sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a vertical longitudinal sectional 35 view taken on the line 44 of Fig.- 3;

Fig. 5 is a fragmentary sectional View of another form of my invention, taken on the line 55 of Fig. 6;

Fig. 6 is a section taken on the line 6-6 of Fig. 5;

Fig. 7 is a view in perspective of one of the brace members illustrating it in its open position; and,

Fig. 8 is a sectional view somewhat similar to Fig. 6, but illustrating a still further embodiment of my invention.

Referring now particularly to Figures 1 to 4 inclusive, the frame 11 of the lamp shade is made up of upper and lower ring members 14 and 15 connected by side members 16. In

Serial No. 466,390.

this embodiment of'my invention the side members may be made of wire and joined to the wire ring members in the usual manner as by soldering, brazing or Welding. The lamp shade may be supported by the usual threaded collar 17 or in any other desired manner.

Fhe covering 12 may be formed as shown of a single strip of flexible material such as celluloid, parchment, or the like, or it may becomposed of a plurality of -sections or. individual panels. In order that the covering may snugly fit the frame 11 I preferably form it with rounded corners 18 and similarly rounded upper and lower edges 19. The brace members 18 are made of spring metal or other resilient material, and may be employed either with or without the usual side wires 16 of the lamp shade frame.

Said brace members are slightly curved in length so that {when they are snapped into locked or engaging position they will effectually clamp or hold the covering on the frame. Each of said members is'preferably formed with a longitudinally extending rib or bead 20 which strengthens the brace and fits over the corner 18 of the covering 12,

and with flanges 24 which bear against the covering. The ends of the brace members are formed with inwardly bent loops or hook portions 21 for engaging the upper and lower ring members 14 and 15, respectively, at the corners thereof.

With particular reference to Figures 2 and. 4, it will be noted that these loop portions 21 have a central cut-away portion or slot 22 so that they may more readily conform to the angles of the corners. The upper loop 21 is bent around the corner of the upper ring member 14 sufliciently far to prevent its accidental displacement, at the same time per mitting of a certain amount of pivotal movement, whereas the lower loop 21 is formed with a lip portion 23 which will permit of its being readily sprung or snapped into position on the lower ring member 1 In Figure 1 I have illustrated the covering 12 in the act of being placed in position upon the frame 11. This view shows the brace member 13 at the left hand end fully attached to the ring members and the succeeding member 13 partially attached, and further shows the mode in which they detachably hold the covering in place on the frame. When it is desired to remove the covering, as for example, in replacing it with a covering of a difierent design, it is merely necessary to put slight pressure against the lip 23 in an outward direction or until the upper end of the lip 23 shall disengage from the lower end of the ring member 15, when the resiliency of the brace member 13 will again cause it to resume its normally curved position.

The brace members illustrated in the form of my invention in Figures 5, 6 and 7 are each formed of two leg portions. In this instance, the inner and outer leg portions 25 and 26 are formed of a single strip of metal and are bent upon each other formin the loop 27 providing a clamp for attaching the brace member to the upper ring member 14-. These brace members are likewise provided with the longitudinally extending ribs or beads 28 and'29 and terminating in flanges 30.

In this modification the legs 25 and 26 are flared or curved in opposite directions as clearly seen in Fig. 7 so as to permit of insertion of the covering 12. The lower end of the leg 25 is formed with a looped portion 31, and the lower end of the leg 26 is formed with a looped portion 32 which is adapted to be sprung over the portion 31 so as to embrace the latter and to clamp the lower ring member 15 therebetween, as well as to bind the covering or panels 12 in place. Instead of being made of a single strip as shown in Fig. 1 the covering 12 may consist of a plurality of individual panels as indicated in Fig. 5. In this embodiment of my invention a rigid frame construction is obtained without necessity of using the usual supporting wires.

When the brace member 13 is in free position with its lower end disconnected, as shown in Fig. 7, the loop 27 will loosely engage the upper ring member 14. When, however, its

lower ends are clamped or locked around the lower ring member 15, the diameter of the loop will be decreased sufliciently to gri the upper ring member and to hold it firmly in proper spaced relation to the lower ring member.

In the embodiment of my invention illustrated in Fig. 8, I form the inner and outer legs 35 and 36 of separate strips instead of one strip as just described.

From the foregoing description it will be apparent that lamp shades constructed in accordance with my invention may be easily assembled, will be rigid in construction when assembled, and will occupy but a small space previous to assembly. Then, too, by reason of its simplicity in assembly, the covering or panelling .may be readily and quickly applied or changed without the aid of any special appliances or tools.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is 1. A lamp shade frame comprising a pair of ring members, and a plurality of braces each consisting of a pair of diverging spring arms clamped to one of said ring members, each of said arms being provided at its free ends with interlocking loop portions adapted to be sprung into engagement with each other for firmly gripping the other of said ring members.

2. A lamp shade comprising spaced ring members, a detachable covering disposed therebetween, and a plurality of resilient brace members each being pivotally mounted on one of the ring members and provided with a loop at its opposite end adapted to snap firmly into clamp position with respect to the other of said ring members, said brace members being further provided with a longitudinally extending and outwardly formed reenforcing bead and a pair of flanged side portions arranged to overlie the covering and securely clamp it against accidental displacement with respect to the ring members.

3. A lamp shade comprising spaced ring members, a covering adapted to be secured therehetween, and a plurality of resilient brace members, each of the brace members being curved lengthwise and provided with loops at both ends, said brace members be ing adapted to be flexed against the covering and to be clamped to the ring members so as to detachably secure the covering in place.

4. A lamp shade comprising a pair of superimposed ring members, a detachable covering disposed therebetween, and a plurality of brace members for maintaining the ring members in spaced relation and for securely clamping the cover thereto, each of said brace members consisting of a pair of substantially similarly formed arms provided with a pivotal loop at one end and clamping portions at the opposite end.

Signed at New York in the county of New York, and State of New York, this 7th day of July A. D., 19.30.
